What is MUCkl ?

MUCkl is a web based groupchat application with focus on ease of
installation and usage. As a user you just need to enter your
desired nickname and start chatting.
MUCkl doesn't need Perl, PHP or MySQL at the server side nor Java at
the client side. It's just plain HTML/JavaScript.

MUCkl uses Jabber technology to handle all communication. It
let's you connect to any predefined MUC-based chat room.
